Preparation and characterization of flurbiprofen-loaded poly(3-hydroxybutyrate-co-3-hydroxyvalerate) microspheres [PDF]

Journal of Microencapsulation, 2008
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) microspheres containing flurbiprofen were prepared by an oil-in-water emulsion solvent evaporation method, in order to develop a particulate drug delivery system for localized administration. A response surface method (RSM) using a central composite design was employed to evaluate the effect of the ...

Assessing the Performance of Biopolymers as Substrates for Flexible Printed Supercapacitors Containing Liquid Electrolytes

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
The fossil‐based substrates of a printed supercapacitor containing liquid electrolytes can only be replaced with biopolymers if they have adequate permeabilities. This article studies three biopolymers based on their processability, printability, and barrier properties to find a more sustainable substrate option.
